Yukon 4340 Chrome Moly Replacement Rear Axle for Dana 80 37 Spline 35.5-39.5in Applications

If you're rebuilding the rear end of a heavy-duty truck equipped with a Dana 80 full-float axle, a strong replacement axle shaft is crucial. This Yukon 4340 Chrome Moly rear axle is built to handle the demands of larger trucks and towing applications.

This axle is made from high-tensile strength 4340 chromoly steel, which is known for its toughness and resistance to bending or breaking under load. Yukon uses cold-rolled splines for improved strength and durability where it matters most, and the shafts are heat-treated to ensure they can withstand significant stress. The cut-to-length design means you can tailor it to fit applications ranging from 35.5 to 39.5 inches, and it features an 8 x 3.96 inch bolt pattern for the brake rotor or drum.

This axle is designed as a direct replacement for your Dana 80 full-float rear axle, ensuring it fits right and performs reliably. Make sure to measure your existing axle shaft length to determine the correct cut length for your specific application.
